As an Envoy flow I can tell you that a lot of guys I spoke with the last couple years have been waiting for AA, mainly for the retirement numbers and given the average age of a new hire at AA was high 30s/low 40s compared with the fact that both UA and DL have already hired 5000ish guys in 7 years with a much lower average age...much better movement plus DFW for those that want it.
As far as the bottom half of the list, those guys we’re asking how to get picked up at any major quickest.
